Niagara Simulation Stage + DynamicMaterialParameters crash

deleting the code "&& SimulationStages[i]->bEnabled" in UNiagaraEmitter::GetScripts will bypass the problem [Image Removed]

1、create a niagara system with a directional burst emitter

2、change the Sim Target to GPUCompute Sim and enable Fixed Bounds of the system

3、enable  Simulation Stage and add a Generic Simulation Stage, then add a Dynamic Material Parameters 

4、deactive the Stage just added

5、compile and save the asset, then reopen it
